Is there any difference between an iPod 5th Generation (80GB, late 2006) and an iPod Classic (160GB, late 2009)?
The 80GB iPod works perfectly with a USA-SPEC PA-12 adapter for a BMW car stereo and a simple 30-pin to USB adapter for input to a receiver. The newer 160GB iPod is not recognized and will not play.
I also have a SONY RDP-X500iP Dock. The newer 160GB iPod works with it, but the old 80GB iPod does not.
Can anyone help me with these two iPods?
